Subject Re: Using scp -- how to find or make a keyfile?
Date Tue, 19 Aug 2008 22:37:03 GMT
Can you post your ant build file (remove any passwords that may be in it),
and the error message?

If you want to use ssh keys for authentication, you need to do the
1. Generate a key pair...
ssh-keygen -d
2. Copy the public key to the remote server.
scp ~/.ssh/ user@host:
3. Add the public key to the authorized_keys file on the remote host for the
user you will connect as....
ssh user@host 'cat >>.ssh/authorized_keys'
4. Test the connection. You should not be prompted for a password...
ssh user@host

If you are prompted with a password, check the permission of the .ssh
directory and it content both locally and on the remote host. Directories
should be 700 and files 600. Public keys can be 644.

I highly recommend reading the man pages for ssh, particularly the
authentication section.
